ABSTRACT
Over the last 2 years, 25 patients with testicular masses detected at clinical examination or US underwent MR imaging, in addition to US. The findings of US and MR were compared. Imaging findings were correlated with the surgical and histopathologic findings. Finally, all MR examinations were retrospectively reviewed after the diagnosis was confirmed. The results showed that four patients were found to have extratesticular lesions and 21 patients intratesticular abnormalities. The extratesticular abnormalities included one case of simple hydrocele, one case of chronic hematocele, one case of infected hematocele with epididymo-orchitis and one case with tumor. The intratesticular abnormalities included malignant tumors [17 patients] and chronic inflammatory disease [4 patients]. Of the 17 patients with malignant tumors, 16 patients were primary and 1 patient with metastasis from Hodgkins disease. Of the 16 primary tumors, 11 patients had seminoma and 5 had non-seminomatous tumors [2 patients with teratoma, 1 patient with embryonal cell carcinoma and 2 patients with mixed germ cell origin]
